Such development in wireless communication technologies and data processing enables users to utilize functions to play contents or to wirelessly connect to the Internet as well as to voice call by utilizing mobile terminal devices.

The mobile terminal devices enable user mobility to overcome the disadvantageous fixed nature of a personal computer. However, mobile terminals are rather limited in memory and battery life, due to their compact size. Thus, users have difficulty in simultaneously implementing searching and playing contents or data by utilizing mobile terminals.

In order to overcome these difficulties, searching and playing processes need to be separated. For instance, users may select or search data with devices that have no limitation in a central processing unit, a memory and a battery, and view the selected or searched data with mobile terminals. Users also may select and search data with mobile terminals and view the selected or searched data with other devices.

However, in order to separately implement data searching and data playing, data should actively be shared among devices. Thus, data should be conveniently shamble by two or more devices so that the data can be implemented or processed in two or more devices. In addition, since the devices have different specifications and working environments from each other, data needs to be processed in consideration of the specifications and working environments of the devices. Therefore, a method to more conveniently share data is necessary.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Embodiments of the present invention will now be described in greater detail with reference to the accompanying drawings.

In the following description, same drawing reference numerals are used for the same elements even in different drawings. The matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of the present inventive concept. Accordingly, it is apparent that the embodiments of the present invention can be carried out without those specifically defined matters. Also, well-known functions or constructions are not described in detail for the sake of clarity and conciseness.

FIG. 1 illustrates a data transmitting system according to the present invention. The data transmitting system selects data from a plurality of data according to user needs, and enables sharing of the selected data with other devices. Additionally, the system transmits the shared data to other connected devices, if the devices are connected to a server.

The data transmitting system may include user terminal apparatuses such as a cellular phone 110, a personal computer 100, a laptop computer 130, a digital camera 140, a television set 150, and a server 200.

The terminal apparatuses not only perform their own roles, but also transmit their own data to the server 200 in order to share the data with other devices.

For instance, the cellular phone 110 transmits webpages searched through web-surfing and stores the webpages in the server 200, while the personal computer 100, which connects to the server 200, calls and displays the stored webpages. Likewise, the digital camera 140 takes photos, transmits the photo data to the server 200, and stores the data in the server 200, while the television set 150, one of the other devices connected to the server 200, calls and displays the stored photos.

The shared data may include all of the data generated or transmitted by the connected devices such as videos, voices, addresses, telephone numbers, and internet-searching data as well as the aforementioned photos and webpages.

As explained above, the server 200 stores the shared data transmitted from the devices through a network, and transmits the data to the devices connected to the server through the network.

The server 200 analyzes information related to the devices connected to the server 200, and determines device access based on information analysis.

The information related to the devices may include user information as well as device information.

The device information may include information on manufacturers, products, MAC addresses, and profiles, as well as other information. The user information may include, for example, information on access authorization to the server 200, security, and user preferred data.

The information on manufacturers is identification information related to the companies that manufactured the device, and the information on products is identification information on the device types. In addition, the MAC address information is a unique identification information determined for each communicable device, and the information on profiles is a collective term for the information on certification and levy regarding the device, the services used by the device, and the communication network to which the device belongs.

The access authorization information reveals the device having an access authorization to the network or to the server while the security information reveals the status of the device security. Additionally, the user preferred data information reveals the data that a device user prefers.

For instance, the server 200 may allow a device to access the server 200 without particular control, if the server 200 finds that all of the connected devices are produced by one manufacturer, or that a user of the connected devices have an authorization to the server 200, based on the device information of the devices connected to the server 200.

Additionally, the server 200 may previously find and store user preferred data through the television set 150, and transmit the data related to the preferred information from the shared data to the television set 150. For example, the user preferred data may be generated based on watching lists of the television set 150, or data lists transmitted by accessing to the server 200 through the television set 150.

The server 200 may check the updated shared data, and provide the shared data to a device when the device connects to the server 200. The shared data is provided when the device connects to the server 200, since connecting to the server 200 may indicate that a user wants to use the connected device. Thus, the server 200 may find that a user wants to use the device when the device connects to the server 200, and transmit the shared data to the device. Transmitting process after accessing the server 200 will be further explained below.

The server 200 may provide the shared data to the device accessing the server 200 based on the device information and the user information as explained above. In order to more efficiently transmit and receive the shared data, each device needs to be registered on the server 200. The shared data may also be provided without registering a device on the server 200. However, if the server provides the shared data to the registered device, the authorization process may be implemented in a simpler manner and the data transmitting and receiving process is customized for the registered device.

The process of registering devices on the server 200 will be described below with reference to FIG. 2.

FIG. 2 illustrates a process of registering device according to the present invention. For example, the cellular phone 110 is registered on the server 200 in FIG. 2.

In order to register the cellular phone 110 on the server 200, at S310, the cellular phone 110 transmits a device registering request to the server 200. At S320, the server 200 receives the device registering request of the cellular phone 110, and transmits device and user information request to the cellular phone 110 in order to determine the possibility of the device registration. At S330, the cellular phone transmits the device and user information to the server 200 in response to the device and user information request.

As explained above, the device information of the cellular phone 110 may include, for example, information on manufacturers, products, MAC addresses, and profiles. Additionally, the user information of the cellular phone 110 may include, for example, information on access authorization to the server 200, security, and user preferred data.

At S340, based on the device and user information received from the cellular phone 110, the server 200 determines whether the cellular phone 100 can be registered, or in other words, whether the received information is available to register the cellular phone 110.

At S340-N, if the registration fails, at S350, the server 200 notifies registration failure to the cellular phone 110, and at S340-Y, if the registration succeeds, at S360, the server 200 notifies registration success to the cellular phone 110. At S370, the server 200 registers the cellular phone 110 on the server 200 and stores information received from the cellular phone 110.

Registering the cellular phone 110 on the server 200 simplifies the authorization process of the cellular phone 110, and thus, a process of transmitting the shared data generated by the cellular phone 110 or received from other devices to the server 200 is expedited. Additionally, registering the cellular phone 110 on the server 200 may enable customization of the cellular phone 110, or in other words, the server 200 may provide the shared data optimized for the cellular phone 110 if the data is transmitted to the cellular phone 110.

FIG. 3 illustrates a list of devices registered on the server 200.

The server 200 arranges registered device list 400, and transmits and receives the shared data more conveniently if the device of the registered device list 400 is connected.

Although FIG. 3 shows product names of the registered device list 400, the server 200 may also store device and user information received from the devices in the registered device list 400.

FIG. 4 illustrates a process of transmitting the shared data according to the present invention. The cellular phone 110 and the television set 150 will be explained as an example.

The cellular phone 110 transmits the data 500 generated by the cellular phone 110 or received from other devices to the server 200 to share the data 500 with other devices.

Transmitting the data from the cellular phone 110 to the server 200 results in the following effects.

The data 500 can be visually provided more conveniently. It is inefficient for plural viewers to view the data 500 with the cellular phone 110 due to a limited display size. Thus, if a user needs to share the data stored on the cellular phone 110 with other users, he or she can store the data 500 in the server 200 and call the data through a device having a larger display, such as the television set 150.

The data 500 can be separately collected and processed more conveniently. The cellular phone 110 is portable and can be used without limitation of place and time. However, it has limited display size and is inconvenient in terms of user manipulation. The user can easily collect data through the cellular phone 110, store the data in the server 200, and process the stored data of the server 200 through the personal computer 100 at home. If a viewer cannot use the television set 150 due to a lack of time, he or she may store the data of the television set 150 in the server 200, and call and watch the data through the cellular phone 110.

The data 500 can also be arranged more conveniently. Each device may have common data despite limited storage. The server 200 can integrate every common data from all of the connected devices, enabling a user to conveniently arrange the data 500.

The server 200 transmits and stores the data 500 generated by the cellular phone 110 or received from other devices. The server 200 transmits the stored data 500 to the television set 150 if the data 500 is called by the television set 150.

As explained above, if the device is registered on the server 200, transmitting and receiving data becomes more efficient.

FIG. 5 illustrates a process of a process of transmitting the shared data according to a registration status according to the present invention.

The cellular phone 110 receives or generates data at S610, and determines if the data is shared at S620. If the data is determined to be unshared at S620-N, the cellular phone find if the data display command is inserted at S630. If the display command is inserted at S630-Y, the cellular phone displays the command at S640.

If the data is determined to be shared at S620-Y, the cellular phone 110 transmits the shared data to the server 200 at S650.

The server 200 stores the shared data from the cellular phone 110 as updated data at S660. If the television set 150 connects to the server at S670, the server determines if the television set 150 is preregistered on the server 200 at S680.

If the television set 150 is unregistered on the server 200 at S680-N, the server 200 transmits a device and user information request to the television set 150, and the television set 150 transmits the device and user information to the server 200 in response to the request at S700.

The server 200 registers the television set 150 on the server 200 at S710. The above explanation shows a brief registering process, but the process may further include additional processes such as those shown in FIG. 2.

If the television set 150 is registered on the server 200 as S710, or the television set 150 is preregistered on the server 200 at S680-Y, the server 200 selects data by analyzing authorization and available applications of the television set 150 based on the stored device and user information received or pre-received from the television set 150 at S720.

Authorization of the television set 150 is analyzed since sharing limitation may be set by the cellular phone 150 providing the shared data.

Applications of the television set 150 are analyzed since all of the data may not be available in every device. Thus, the server 200 previously finds available data types that can be implemented on the television set 150 based on the device and user information, and transmits the available data to the television set 150.

Additionally, the server 200 processes the selected data based on the device and user information received or previously received from the television set 150 at S730. Processing data may include, for example, scaling data, optimizing data to the resolution of the television set 150, and arranging data size to implement on the television set 150.

The server 200 transmits the processed data to the television set 150 at S740. The television set 150 displays the data upon receiving at S750.

The television set 150 receives and displays the updated shared data upon connected to the server 200, enabling a viewer to watch the updated shared data without delay.

As explained above, the server 200 may automatically transmit the updated data of the server 200 to the devices upon connected to the server 200. According to the foregoing embodiment, the television set 150 may not provide a user with data unavailable on the television set 150 since the unavailable data are not transmitted to the television set 150. Thus, the server 200 determines whether other devices can implement the non-transmitted data upon connection to the server 200, and transmits the data to the newly connected device if the data are available on the device.

FIG. 6 illustrates a list of devices registered 800 on the server 200. As explained above, since the server 200 arranges the registered device list 800, the server 200 transmits and receives the shared data more conveniently if a device included in the registered device list 800 connects to the server 200.

Particularly, as shown in FIG. 6, the server 200 detects specific information such as authorization level or resolution of the devices based on the device and user information, and manages the detected information with the registered device list 800, which can be applied to analyzing device authorization and available applications of the devices, and to processing data.

FIG. 7 illustrates a process of transmitting the shared data according to a preprocessing status according to the present invention.

At S910, The cellular phone 100 receives or generates data, and at S920, determines if the data is shared. At S920-N, if the data is determined to be unshared, at S930, the cellular phone 110 finds if the data display command is inputted. If the command is inputted at S930-Y, the cellular phone 110 displays the command at S940.

Meanwhile, if the data is determined to be shared at S920-Y, the cellular phone transmits the data to the server 200 at S950.

The server 200 stores the shared data received from the cellular phone 110 and set the data as updated at S960. The sever 200 determines a pre-processing status of the updated shared data before a device connects to the server 200 at S970.

Preprocessing status of data may be determined according to setting input from a user.

If the data is determined to be pre-processed at S970-Y, the server 200 processes the updated shared data according to the registered device information. For instance, the server 200 may register the cellular phone 110, the personal computer 100, the laptop computer 130, the digital camera 140, and the television set 150. The server 200 may process the updated shared data to be optimized for the cellular phone 110 based on the device and user information received from the cellular phone 110, the server 200 may process the updated shared data to be optimized for the personal computer 100 based on the device and user information data received from the personal computer 100, the server 200 may process the updated shared data to be optimized for the laptop computer 130 based on the device and user information received from the laptop computer 130, the server 200 may process the updated shared data to be optimized for the digital camera 140 based on the device and user information received from the digital camera 140, and the server 200 may process the updated shared data to be optimized for the television set 150 based on the device and user information received from the television set 150.

Additionally, if the data is determined to be preprocessed at S970-Y, the server 200 selectively processes the updated shared data according to registered devices. For instance, if the data is unavailable on the television set 150, the server 200 may not process the updated shared data so as to transmit the data to the television set 150.

After completing processing the updated shared data, the server 200 stores and arranges the processed data until devices connect to the server 200.

If the television set 150 connects to the server 200 at S990, The server 200 transmits the processed data optimized for the television set 150 to the television set 150 at S1020, and the television set 150 displays the received data on a screen at S1030.

FIG. 8 illustrates the shared data processed according to devices.

Referring to FIG. 8, the cellular phone 110 takes a photo and transmits the photo data 1110 to the server 200 to share the data with other devices. The photo data has a resolution of 800*600.

The server 200 processes the received shared data based on the device and user information received from devices. If the digital camera 140 having a resolution of 1000*500 and the television set 150 having a resolution of 1920*1080 are registered on the server 200, the server scales and converts the shared data to the data having a resolution of 1000*500 based on the device and user information of the digital camera 140 while the server scales and converts the shared data to the data having a resolution of 1920*1080 based on the device and user information of the television set 150.

If the television set 150 connects to the server 200, the server 200 transmits the processed data having a resolution of 1920*1080 to the television set 150.

Converting resolution is one of several embodiments of what is disclosed herein. Converting for the optimized implementation of data in devices such as converting file formats, converting file size may also be included.

If the data is determined to be non-preprocessed at S970-N, the server 200 stores the data without processing the updated shared data and arranges the data until devices connect to the server 200.

If the television set 150 connects to the server 200 at S990, the server 200 analyzes authorization and available applications of the television set 150 based on the device and user information received from the television set 150, selects the shared data available on the television set 150 at S1000, and processes the selected data to be optimized for the television set 150 at S1010.

The server 200 transmits the optimized data to the television set 150 at S1020, and the television set 150 displays the data at S1030.

A user may select preprocessing or non-preprocessing for the updated shared data. The server 200 more quickly transmits the devices upon being connected to the server 200 while the server 200 uses a large amount of storage capacity since the server 200 stores the processed data in each device.

FIG. 9 illustrates a process of transmitting the shared data according to the present invention.

The cellular phone 110 receives or generates data at S1210, and determines if the data is shared only with the television set 150 at S1220. If the data is shared with other devices than the television set at S1220-N, the cellular phone 110 finds if the data display command is inputted at S1230. If the display command is inputted at S1230-Y, the cellular phone displays the command at S1240. A process to set the data to be shared with other registered devices on the server 200 than the television set 150 may also be added.

If the data is shared only with the television set 150 at S1220-Y, the cellular phone 110 transmits the data, which are limitedly shared with the television set 150, to the server 200 at S1250.

The server 200 stores the data received from the cellular phone 110, and sets the data as updated and as shared only with the television set 150 at S1260.

The server 200 analyzes authorization and available applications of the television set 150 based on the device and user information received from the television set 150 and processes the data to be optimized for the television set 150 at S1260.

If the television set 150 connects to the server 200 at S1270, the server 200 transmits the preprocessed data to the television set 150. Since the processed data is only shared with the television set 150, the server 200 does not transmit the data to other devices even if the devices connect to the server 200.

FIG. 10 illustrates data 1300 stored on the server 200 according to the present invention.

As explained above, the server 200 stores the data updated and transmitted from devices registered on the server 200. Data transmitted from devices and shared with other devices may also be stored on the server 200.

Meanwhile, the server 200 stores data with information on data sharing limitation. For instance, DATA 1 is shared with all of the devices while DATA 2 is shared only with the television set 150, and DATA 3 is shared with devices excluding the television set 150.

Thus, data can be shared according to user manipulation, resulting in protecting user privacy.

Meanwhile, the server 200 stores data based on metadata. The server 200 generates metadata from the received shared data, and stores the metadata with the corresponding shared data. Thus, each device may input a specific keyword, and search and select data to be transmitted to the other devices.

FIG. 11 illustrates a process of providing the shared data based on the metadata according to the present invention. The server 200 stores the shared data from devices and generates metadata from the shared data at S1430. The server 200 stores the metadata with the corresponding shared data at S1440.

FIG. 12 illustrates a process of generating metadata according to the present invention.

Referring to FIG. 12, if the cellular phone 110 transmits the shared data 1610 to the server 200, the server 200 stores the received shared data 1610, generates the metadata 1620 from the shared data 1610 and stores both the shared data and metadata.

For instance, in FIG. 12, metadata MOVIE is generated from the received shared data based on genre information; metadata E.T. based on title information; and metadata OLD based on date information.

Any other information generated from the shared data 1610 than genre, title and date may be metadata. Thus, symbol, number, figure or color constituting the data, or domain names of webpages including or searching data may generate the metadata.

Thus, as explained above, each device may select and search the data to be transmitted to the other devices by inputting keywords.

In FIG. 11, if a user input a keyword to the cellular phone 110 at S1410, the cellular phone 110 transmits the keyword to the server 200 at S1420, the server 200 analyzes the metadata of the shared data stored on the server 200 based on the keyword, and selects the shared data corresponding to the metadata at S1450.

Additionally, the server 200 select some of the registered devices by analyzing metadata based on the keyword at S1460, and processes and stores the selected data in an optimized format for the selected devices at S1470.

The server 200 determines whether other devices connect to the server 200. If the television set 150 connects to the server 200 at S1480, the server 200 transmits the processed data with the metadata to the television set 150 at S1490, and the television set 150 displays the processed data on the screen at S1500. The server 200 may also transmit the processed data to the television set excluding the metadata.

FIG. 13 illustrates transmitting the shared data based on keywords according to the present invention.

If a user inputs the keywords 1710 such as MOVIE, E.T., and OLD to the cellular phone 110 and transmits the keywords 1710 to the server 200, the server 200 searches the shared data based on the keywords 1710 and generates the searched data 1720.

Additionally, if the cellular phone 110 has a command of transmitting the searched data, the server 200 finds devices connected to the server 200, and transmits the shared data 1730, or in other words, transmits the searched data 1720, to the television set 150 connected to the server 200.

As explained above, the shared data generated or received by the cellular phone 110 is stored on the server 200, and the server 200 transmits the shared data to the television set 150 upon connecting.

Since a user begins to use devices upon getting connected to the server 200, the server 200 transmits the shared data to devices when the device is connected to the server 200. Transmitting the updated data to a device upon connecting to the server 200 enables a user to conveniently find the updated data without having to input any other manipulation.

Since home devices can be used by plural users, a user of the cellular phone 110 can be different from a user of the television set 150. It often occurs that a viewer of the television set 150 connected to the server 200 is different from a user who is finding updated data through the television set 150.

Checking the updated data may inconveniently disturb the viewer who wants to watch the television set 150 only.

In order to solve this inconvenience, a user may be required to choose whether to display the received updated data.

Referring to FIG. 14, when the television set 150 connects to the server 200 at S1810, the server 200 transmits the shared data to the television set 150 at S1820.

Since a user storing the shared data in the server 200 may be different from a user manipulating the television set 150, the television set provides the UI to inquire if the television set 150 displays the shared data at S1830.

If a user inputs display command at S1840-Y, the television set 150 displays the shared data at S1870. If a user does not input display command at S1840-N, the television set 150 informs the server 200 that the shared data are unprovided at S1850. The television set 150 may also store the shared data in the television set 150, or may delete the shared data in the television set 150.

Since the shared data are not provided with the user, the server 200 detects other devices at S1860, and transmits the shared data to the connected devices.

FIG. 15 illustrates a process of displaying the metadata corresponding to the shared data according to the present invention.

In FIG. 15, a user searches a plurality of online shopping malls through the cellular phone 110, generating plural data, and transmits the plural data to the server 200 for sharing. The cellular phone 110 displays one of plural data that a user searches.

If the user sets the plural data as shared data, the data are transmitted and stored in the server 200.

The server 200 generates metadata corresponding to the shared data and stored both of them. In FIG. 15, a user searches a Banana costing $10.00 in a online shopping mall, B-Mall, and a server 200 stores a searched webpages as shared data.

The server 200 generates metadata such as B-Mall or Banana from the searched webpages.

Additionally, the server 200 generates metadata from searched webpages of a A-Mall and a C-Mall and stores the shared data with the metadata.

If the user connects to the server 200 with the personal computer 100, the server 200 transmits the updated shared data to the personal computer 100. If the server 200 finds that the capacity of the data received from the cellular phone 110 is high or that the data received from the cellular phone 110 have interrelationship to each other, the server 200 transmits the metadata to the personal computer 100 without the data.

The personal computer 100 displays the metadata corresponding to the updated shared data on one screen, enabling a user to select and download the shared data through the personal computer 100.

For instance, if a user needs to download the searched data of the B-Mall from the shared data, the user can select metadata indicating B-Mall on a screen. If a user selects one of the metadata indicating B-Mall, the server 200 provides the personal computer 100 with the shared data searching the B-Mall.

As a result, the personal computer 100 displays the same contents searched by the cellular phone 110.

Thus, a user can conveniently select data while carrying with the cellular phone 110 and utilize the data easier and faster while using the personal computer in a convenient environment since the personal computer 100 receives the shared data from the server 200 that the cellular phone 110 generates.
